Description
8/2-WIRE interface is a device that can be used for installing mixed video door entry
systems, with common backbones using the digital system (8 WIRES), and risers using
the 2 WIRE system.
It is ideal for very large systems as all the performance advantages of the digital system
can be combined with the installation advantages of the 2 WIRE system (simple wiring
system, intercommunication, no need for local power supply of monitors).
The device must be used together with the 346000 power supply.
In installing a system with local entrance panel, the entrance panel itself may be wired
using both the 2 WIRE, or the 8 WIRE procedure.
